How does it compare to Grafana?
1oooqooq wrote 14 hours 23 min ago:
why would you do that in a single threaded language like nodejs?
seems like an awful decision
throwaway11460 wrote 14 hours 16 min ago:
Why not? Single threaded doesn't mean only a single thread is ever
used.
Also, if I understand it correctly, this is a web frontend. Node.js
is used for development (bundling, testing etc).

They even have a plugin to get Kerbal Space Program telemetry[1]! Could
be useful I guess if you want to play without the HUD on one screen and
have all the mission info on a second screen.

iâve wanted to play KSP with telemetry visualisation and basic
remote commands only for a while. i guess that makes me a masochist,
but you could say the same of enjoying KSP at all.

I love OpenMCT, in 2021 I wrote some crypto DeFi arb trading bots (just
doing realtime graph constructions and then bellman ford, then a
hill-climbing amount optimiser and gas estimator and transaction
obfuscator to help avoid sniping)
I modified OpenMCT to be the GUI for this, which showed the profitable
trading paths through the graph in realtime.
I emailed NASA to ask if they could put my thumbs up, mugshot on their
users page next to all of the satellites and Mars missions, they said
they couldnât because my project was a for profit enterprise, but I
totally think they just didnât want my (insane) mugshot there XD

Could you expand on your trading bot?
To bad for NASA denying your mugshot. I bet it would have generated
many stars on GitHub.

What I wrote above is basically the summary, it crawled the mempool
and checked the address interfaces to discover Defi exchanges
automatically.
I found maybe 20-30 exchanges that were not publicly advertised, so
there was quite a bit of liquidity there. It looked for triangular
arbitrage opportunities, then optimised the amount and computed gas
costs to check if it was profitable. There was a lot of compute
required, about 12,000 paths a second were searched and a
profitable trade would be found about once every 3 hours.
âOptimising the amountâ was a bit tricky too - too little you
leave money on the table, too much you cause slippage - but you
know the good thing about DeFi is that through our ETH nodes we
have a copy of the blockchain and I had already written an EVM
disassembler for another project, so I had a lot of knowledge of
EVM internals - so I could simulate the trade executions inside the
optimiser locally, which greatly helped ârealismâ
The whole system was profitable for about 8 months, it netted me
about 180k usd before it tapered off - I donât know why but I
suspect someone else found the strategy/was doing the same thing,
so I took the cash out of it, paid tax and moved on.
If youâre interested in the tech it was all just pure Python,
networkx for the graph stuff, shared memory, multiprocessing and
lots of IPC, the whole thing operated in RAM because it has to be
quick (exponential number of paths to search) - anything important
(debugging / trade execution) was thrown in a queue and written out
by another process
After that, I built this

Thanks, that was a lot of insight, I appreciate it. Congrats for
finding and executing a profitable strategy.

Haha all good if you get it to work and make 100M then throw me
a million down from your yacht will you?

There's a NASA funding line called Tipping Point used to
commercialize NASA tech. I bet you couldve buttered up the managers
of that fund during the defi hayday and gotten a small pot to work on
it.
